Hiper Power Type M 780W Reviewpaulktreg - November 5, 2008

The use of recycled paper for the main box and user manual, along with sparing use of packaging materials is to be commended. Granted, the box doesn't look pretty, and anyone who likes packaging to be colourful and shiny is going to be dissapointed with the Hiper. But, combine this with high efficiency and a good power factor, and I have to award this power supply with some good marks for environmental consideration.
Price Per the Watt:
Power Supply Hiper Power Type M 780W at $134.99 = $0.17/Watt (October 2008)
One of my major concerns, especially with the overclocker in mind, is the design of the cooling system on the Hiper Power Type M 780W. The major enemy of any overclocker is heat, and the last thing needed is a power supply returning air back into the case at an higher temperature than it was removed. This, I feel sure, will happen with the Hiper unit, as air from the case will be drawn in by the fan and it will exit not only from the rear, but also the grilled side panels, and straight back into the case. This is my main reason for not doing any temperature testing. With the warm air exiting the unit on four sides, would temperature measurements really mean anything?
The efficiency of the unit, taking no other factors into account, is pretty good, but the claimed 80 Plus Bronze certification on the website was not met during my testing. I could find no mention of 80 Plus certification on the packaging or accompanying literature, so I can only presume it is a recent accreditation. The noise level on the 12V rail at full load is marginally higher than the ATX12V specification allows for at 130mV against the 120mV permitted. This will have little or no effect on the motherboard and operation of any PC, but is nonetheless slightly higher than permitted.
There's no doubt that the Hiper Power Type M 780W is a quality, well made power supply, but I could not recommend its use by any of you overclockers out there, mainly because of the issues with heat. Heat is the biggest factor when it comes to overclocking any PC, and a power supply adding to this problem is something I imagine most overclockers can do without. That said, if you are after a power supply to run your high performance gaming system at stock with dual 8800GTX graphic cards in SLI, then I feel sure the Hiper Power Type M 780W will cope admirably with good case cooling.
